Title (EN) TONER, AND TONER PRODUCTION PROCESS
(FR) TONER ET SON PROCESSUS DE PRODUCTION
Abstract:
(EN) In a chart of molecular weight distribution measured of a toner, i) the toner has a main peak in the region of molecular weight of 16,000 to 60,000, and ii) where the molecular weight at the main peak is represented by M1, and where the height at the molecular weight M1 is represented by H(M1), the height at a molecular weight of 4,000 by H(4000) and the height at a molecular weight of 15,000 by H(15000), the H(4000), the H(15000) and the H(M1) satisfy a specific proportion. The toner has a weight average molecular weight (Mw) of 15,000 to 80,000, and, in an endothermic chart, i) the toner has an endothermic main peak in the range of 40 to 130 C, and ii) the calorimetric integral value represented by the peak area of the endothermic main peak is 10 to 35 J per 1 g of the toner.
(FR) Dans un graphique de distribution du poids moléculaire mesurée d'un toner, (i) le toner possède un pic principal dans la région de poids moléculaire comprise entre 16000 et 60000 et (ii) le poids moléculaire au niveau du pic principal est représenté par M1 et la hauteur au poids moléculaire M1 est représentée par H(M1), la hauteur à un poids moléculaire de 4000 par H(4000) et la hauteur à un poids moléculaire de 15000 par H(15000), H(4000), H(15000) et H(M1) satisfont une proportion spécifique. Ledit toner a un poids moléculaire d'indice de pondération (Mw) compris entre 15000 et 80000 et, dans un graphique endothermique, (i) le toner présente un pic principal endothermique allant de 40 à 130 °C et (ii) la valeur intégrale calorimétrique représentée par la zone de pic du pic principal endothermique va de 10 à 35 J pour 1 g du toner.
